Definitions

  • the present invention relates to insulation displacement contact (IDC's), and more particularly to an improved IDC having means for controlling slippage of a wire terminated therein when the wire is subjected to small movements.
  • IDC insulation displacement contact
  • IDC's have been around for a long time and are very popular. This popularity is due in part to their ease of use, economy, versatility, and effectiveness. For many applications, IDC designs have reached a state of considerable refinement.
  • the present invention meets the above needs and purposes with a new and improved insulation displacement contact, and in particular such an insulation displacement contact in which its wire-receiving slot has a unique detent provision for retaining a wire therein after the wire has been pushed into the slot.
  • the detent is a boss which intrudes into the slot to form a narrower passage in the slot at that location.
  • the boss is preferably formed by stamping followed by coining, although the process which is chosen will depend upon the desired IDC dimensions, the thickness of the metal plate from which the IDC is formed, and so forth.
  • a bump is first formed by stamping, and then enlarged by punch coining to the desired dimension. (Punch coining refers to coining by striking with a defined punch geometry.)
  • the insulated wire is then pushed into this slot, causing the insulation thereon to be displaced and completing an electrical connection to the IDC.
  • the wire is progressively pushed farther into this slot, it is forced past the detent. This results in a more stable and reliable termination for the wire since it will now not easily escape from the slot if subsequently subjected to small movements.
  • the detents are staggered so that wires which are being simultaneously terminated in the slots will progressively encounter the detents, one at a time, to make insertion and removal of the wires easier.
  • the insulation displacement contact includes a bridge, a pair of adjacent arms depending from the bridge and defining therebetween a conductive slot configured for receiving an insulated wire, for displacing the insulation thereon, and for completing an electrical connection thereto, and wherein at least one detent in the slot depends from at least one of the arms for retaining a wire therein after being pushed into the slot past the detent; in which the detent may include a boss intruding into the slot to form a narrower passage in the slot in the vicinity of the boss; in which the boss may include a bump formed by stamping; in which the boss may include a bump formed by stamping followed by coining; in which the boss may be a bump formed by coining; in which the boss may be a bump formed by punch coining; in which the contact may include a second pair of adjacent arms depending from the bridge and defining therebetween a second conductive slot configured for receiving an insulated wire,
  • FIG. 1 is an isometric illustration of an insulation displacement contact having wire slippage and movement control according to the invention
  • FIG. 2 is an elevation of the FIG. 1 contact
  • FIG. 3 is an enlarged fragment of the connector of FIGS. 1 and 2;
  • FIG. 4 is a cross-sectional view taken on line 4--4 in FIG. 3.
  • FIG. 1 is an isometric illustration of such an insulation displacement contact 10.
  • contact 10 includes a pair of arms 12a and 12b depending from a bridge 14. Arms 12 thus define a conductive slot 15 configured for receiving an insulated wire (not shown), displacing the wire's insulation, and completing an electrical connection thereto.
  • the IDC 10 is formed by stamping from a sheet of copper alloy metal.
  • detent 20 In slot 15, and depending from either arm (in this case, arm 12b), is a detent 20 for retaining a wire in slot 15 after the wire is pushed into the slot past the detent 20.
  • detent 20 is a boss which intrudes into the slot to form a narrower passage 23 in the vicinity of the boss 20.
  • the boss can be formed by any conventional process, depending upon the dimensions and preferred characteristics. These include stamping, coining, punch coining, or any combination thereof.
  • the particular IDC configuration illustrated herein is an improvement on the IDC shown in U.S. Pat. No. 5,423,694, issued Jun. 13, 1995, and assigned to the assignee of the present invention.
  • the disclosure of U.S. Pat. 5,423,694 is therefore incorporated herein by reference for all purposes.
  • That '694 patent shows an IDC having multiple slots for simultaneously terminating several wires, preferably one per slot.
  • the present invention includes a second pair of arms 32a and b also depending from bridge 14 to define a slot 35 similar to slot 15.
  • Slot 35 includes a detent 40 similar to detent 20, except that detent 40 is farther from bridge 14 than detent 20. This staggers the detents to reduce insertion and removal forces, particularly when used in a terminal block such as shown in the '694 patent.
  • the present invention provides numerous advantages. Principally, it provides added security for keeping a terminated wire in the slot when the wire is subjected to small vibrations and/or movements.
  • the block when used in a terminal block such as shown in the '694 patent, it is intended that the block may be manipulated from time to time to, for example, add additional wires thereto. At such time, previously installed wires may be subjected to movement during this installation process. Preferably, these wires would remain terminated in their IDC slots. With the present invention, this is much more reliably assured, since minor wire movement will now not generate sufficient force to move the wire back past the detent where it might then exit from the slot.
  • Another advantage of the invention results from the staggered spacing of the detents within their slots, so that the wires progressively encounter the detents, thus reducing insertion and removal force.
  • the invention thus provides a straightforward, economical, robust, and highly effective solution for assuring that a wire which is terminated in the IDC will remain in the IDC until a definite decision is made to remove it.
